Photo Stream looks pretty great, and I cant wait to have all my pictures show up on all my devices without having to sync them over... BUT; does anyone know if we can ADD photos manually to the photostream without actually taking the picture? Eg. Im on vacation, and I have just taken a bunch of pictures with my Nikon camera, I get back to the hotel, move my pics over to the iPad with the Camera connection kit (SD card reader), and ideally, the rest is "magical".... Also, were there any API's released for Photo Stream ? Hopefully Apple will open it up so Instagram etc, could get in on the action if they wanted to.
